CVE-2019-16232

Published: 11 September 2019

drivers/net/wireless/marvell/libertas/if_sdio.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference.

From the Ubuntu Security Team

It was discovered that the Marvell 8xxx Libertas WLAN device driver in the Linux kernel did not properly check for errors in certain situations, leading to a NULL pointer dereference. A local attacker could possibly use this to cause a denial of service.
